V&r. limbata, Baker (C. limbata, Roscoe. C. 

 aureo-vittata^odd.). Upper staminodia bright red, with a

in. long ; 3 upper 

 in. long but nar- 



350 



Var. flav6scens, Baker (C. flarfxrens, Link). Upper 

 staminodia and the lip entirely yellow. With C. orien- 

 talis probably belong C. densifolia, Ehrenbergii, exigua, 

 ft tan His and pulchra of Douche". 



6. coccinea, Miller (C. riiftra, Willd.). Stem slender, 

 green, 4-6 ft. : Ivs. longer than those of C. Indica, oblong

 with red; petals lanceolate, l%in. long, tinged with red; 

 staminodia 2 in. long and narrow, often emarginate; lip 

 red-yellow: capsule globose and small. Trop. Amer. To 

 this species Daker would refer C. cinnabarina, formosa, 

 fidgida, Portoricensis and Surinamensis

Mexicana and 



the following: C. floribunda, la>ta, recurvata, saturate-

 veutricosa of Douche". C. occidentalis , Roscoe, has only 

 2 staminodia, petal-like. 



5. orientalis, Roscoe. Stem slender, glabrous, 3-4 ft. : 

 Ivs. oblong-lanceolate, a foot or more long : raceme lax, 

 simple or forked, the bracts oblong : sepals oblong-

 ceolate, %in. long; petals lanceolate, Kin. long, colored ; 

 staminodia not much longer than the petals, scarlet; lip
